diallyl ethers 10, from the vinylogous O,S-acetals 13, and from the O,S-acetals 14 by treatment with nBuLi (in the case of 10) or with lithium naphthalenide (in the case of 13 and 14). [2,3]-Wittig rearrangements ensued whose syn,anti-selectivity was studied.
通过用n BuLi处理,由二烯丙基醚10,乙烯基O,S-乙缩醛13和O,S-乙缩醛14生成具有顺式或反式阴离子部分的锂化二烯丙基醚。的10)或萘基锂(在的情况下,13和14)。随后研究了[2,3] -Wittig重排,其合成,反选择性得到了研究。
